Skyrme相互作用被用于一些轻核和稀土核的形变Hartree-Fock计算。本文提出了一种求解方法，它尽可能利用Skyrme力的简单特性，以便计算重变形核。在稀土区域的配对相关性考虑在一个简化的，但自洽的方式考虑能量泛函也取决于占领概率。计算了双闭壳层核研究中所用的两组参数。提供最佳的适合球形核的基态性质的集合也被发现给一个令人满意的描述核变形。在轻核的情况下，与其它可用的Hartree-Fock计算作了比较，并讨论了核形变有效力中各项的重要性。
Skyrme's interaction is used in deformed Hartree-Fock calculations of some light and rare-earth nuclei. A method of solution is presented, which exploits as much as possible the simple features of the Skyrme force in order to allow calculations of heavy deformed nuclei. In the rare-earth region pairing correlations are taken into account in a simplified but self-consistent way by considering energy functionals depending also on occupation probabilities. Calculations have been made for the two parameter sets which were used in a previous study of double-closed-shell nuclei. The set providing the best fit to ground-state properties of spherical nuclei is also found to give a satisfactory description of nuclear deformations. Comparison is made with other available Hartree-Fock calculations in the case of light nuclei, and a discussion of the importance of various terms in the effective force upon nuclear deformations is given.
